Top 20 JavaScript Open Source Projects On GitHub [2024]


JavaScript is one of the most versatile languages in popular use today. It owes its popularity to the fact that JavaScript, along with HTML and CSS forms the core of the World Wide Web, thus enabling us to visualize the internet as we know it today.

Although it was initially designed to serve as a language for scripting front-end web applications, it has evolved to have an almost ubiquitous presence in the world of development. It should, therefore, come as no surprise that JavaScript is the most used language by users of GitHub, which is the world’s largest software development and sharing platform.

GitHub is presently the de-facto platform to share code and open source projects, and naturally, a number of projects are written in JavaScript. In this article, we will take a look at some of best open source JavaScript projects on GitHub.

React – a JavaScript open source library by Facebook

React is one of the top JavaScript open source projects.

React is arguably one of the most widely used open source projects in the world. Created by Facebook, this library makes creating user interfaces in web applications effortless. It also makes developing new features extremely easy, and JavaScript developers do not have to worry about changing any pre-existing code.

React Native, which is built on top of React, extends the functionalities of React to mobile applications, making React a widely used platform for development.

With the increased interest in machine learning in the past few years, there has been a lot of activity around building better libraries to make creating machine learning models easier. TensorFlow.js is the JavaScript version of the well-known TensorFlow library, which was originally written in Python.

By converting it to JavaScript, it is now possible to build and deploy machine learning models in web applications, thereby making them mobile. TensorFlow.js can train machine learning models in the browser itself, which relieves the server of the computational expenses incurred in training the model.

This can also be extended to mobile applications, although the computational power of mobiles is generally too low for machine learning applications.

Node.js is one of the top JavaScript open source projects.

Node.js is an Javascript Open source runtime environment. It is built on the Chrome browser’s V8 engine. Without a separate runtime environment, JavaScript can only be run using the environments of browsers. But Node.js enables JavaScript to be used as a standalone scripting language, like Python.

Developers can now test JavaScript on their own machines, instead of having a browser do it for them. This extends the capabilities of JavaScript from only making websites more interactive to just about anything.

AngularJS is one of the oldest Front-End JavaScript open source frameworks in the industry. Initially developed by Miško Hevery, this widely used framework is among the top 10 starred JavaScript projects on GitHub.

Web applications developed by Angular are cross-platform, in that they are compatible across a wide class of devices, be it Mobiles, Desktops or Tablets. AngularJS is on par with the other frameworks in terms of speed, performance and scalability.

AngularJS advertises to provide huge data requirements and a scalable infrastructure that supports large-scale applications, such as that of Google’s.

jQuery is an open source library that makes client-side HTML scripting easier. Its motto is “Write less, do more”, and it does exactly that. It wraps the most common JavaScript tasks and wraps them into methods. This makes writing code easier and more productive. Estimates put jQuery as the highest used library in web pages.

Meteor is one of the top JavaScript open source projects.

Meteor is a cross-platform open-source platform for web, mobile and desktop. Meteor integrates with various other JavaScript frameworks seamlessly. MeteorJS focuses on optimizing code size, cross-platform compatibility, and integration into other libraries.

Unlike other frameworks, Meteor is not limited to front-end web applications. Meteor enables rapid prototyping and automatic catering of data changes. It also provides a large interface of enhancements readily available for many use cases.

Jest is one of the top JavaScript open source projects.

Jest is a new JavaScript open source testing framework by Facebook, and it works really well with React.js. It aids in detecting bugs and testing is an integral part of any development process. The biggest advantage of Jest over other testing suites is that it requires minimal configuration to start testing your application.

The response has been very positive to this project, and many are shifting to Jest as their testing suite.
